MOTOR-ENGINE WORKED BY THE VAPOR 0F ETHER OR OTHER VOLATILE LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 451,342, dated April28, 1891.

Application filed December 11, 1890. Serial No. 374,378. (No model.)

To aZZ whom it may concern: 7

Be it known that I, PAUL DE SUsINI, a citizen of France, residing atParis, France, have invented certain new and useful Improvements inMotor-Engines \Vorked by the Vapor of Ether or other Volatile Liquids,of which the following is a specification.

In the specification to an application filed August 7, 1890, Serial No.361,252,I described a construction of motor-engine worked by the vaporof ether and other volatile liquids, wherein both the vapor-generatorand the motor-engine, as also the pipes connecting the former with thelatter, were inclosed by casings filled with glycerine or other suitableliquid, which was made to circulate from the one casing to the otherthrough pipes.

According to my present invention I avoid the use of a large body ofglycerine, which is comparatively expensive, by entirely separating thetwo casings inclosing, respectively,

the motor-engine and the generator and only filling that for the formerwith glycerine, while that for the latter is filled with water. Thecasing containing the generator is heated by the fire and the glycerinein the other casing is heated by providing in connection therewith achamber communicating with the water-casing by circulating-pipes, sothat the heatedwater circulates through the said chamber, and thusimparts the required heat to the glycerine.

I will describe the invention with reference to the accompanyingdrawing, which shows a vertical section through the motor-engine andgenerator with their casings and communieating pipes.

A B are the two single-acting open-ended motor-cylinders, whose pistonsO D are connected by rods 0 c to a cross-head E, acting upon thecrank-pin F of a plate G on the engine-shatt H, the engine beingconstructed and operating in precisely the same way as described in myformer application, and consequently not requiring further description.

Q q is the vapor-generator communicating with the cylinders of themotor-engine by the pipe P and passages 19, and M is thesurroundingcasing filled with water heated by a furnace O, and K is thecasing of the motor-engine -filled with glycerine and provided with atubular extension L, also filled with glycerine, inclosiug thevapor-pipe I, and p a return-pipe connecting the bottom of the casing Kwith the lower end of the tubular eX- tension L, thus forming a completecircuit or thermosiphon, through which the glycerine circulatescontinuously.

Below the casing K is a closed chamber ,9, communicating at top by apipe 0:, with the top of the casing M and at bottom by a pipe 7' withthe bottom of the casing M. The chamber [3 and pipes a y being alsofilled with water, it will be seen that they form with the casing M asecond circuit or thermosiphon, through which the water heated by thefire at O circulates continuously. The casing K has pendent tube Kprojecting down into the chamber [1, and which, being filled withglycerine, effectually takes up the heat from the water in the chamberand communicates it to the body of the glycerine in the casing K. Anexpansion-chamber 9, having a safety-valve 0', is provided on the pipe0: of the water-thermosiphon, so as to prevent any dangerousaccumulation of pressure, and a similar expansion-chamber withsafety-valve Zis provided on the tubular extension L of,

the glycerine-thermosiphon forpreventing all excessive pressure thereinwhich might occur until the glycerine is completely dehydrated.

R is the pipe leading the exhaust-vapors from the exhaust-passages s sof the motorengine to a condenser, which may be of any suitable knownconstruction, such as that described in my said prior application. Onaccount of the economy effected in the quan- .tity of glyeeriue used,the above-described construction is more particularly applicable tolarger motor-engines.

Having thus described the nature of this invention and the best means Iknow of for carrying the same into practical effect, I claim- 1. In anether-vapor engine, the combination of a vapor-generator, a casingiuclosing the same filled with water or other suitable liquid, a furnacefor heating such liquid, so as to volatilize the ether, a motor-engineworked by the ether-vapor from the generator, a casing iuclosing themotor-engine and the pipe conveying the ether-vapor to it and filledwith glycerine or other suitable liquid,

and a chamber communicating by pipes with the casing of thevapor-generator, so that the hot water can circulate from the latter tothe former, such chamber being in contact with the casing inclosing themotor-engine, so that the heat of the Water in the chalnberistransmitted to the glycerine in the casing, of the motor-engine and oftheconduit-pipe, substantially as described.

2. In an ether-vapor engine, a casing surrounding the vapor-generatorfilled with water or other suitable liquid, a furnace for heating thewater in the said casing, a casing surrounding the motor-engine and thecouduit-pipe for the supplyof ether'vaporthereto, such casing" beingfilled with glycerine or other suitable liquid, a chamber forming partof the said casing communicating by two pipes with the casing inclosingthe vaporgenerator, so that the heated Water in the last-named casingcan circulate through the said chamber, and thereby heat the glycerineor other liquid in the casing to which it is connected, and a pipeconnecting the lastnamed casing with the end of the casing surroundingthe vapor-supply pipe next the vapongenerator.

3. The combination of ether-vapor generator Q, vapor-supply pipe P,motor-engine A B and parts connected therewith, casings M L K [1, filledwith liquid heated by fire-grate O, and connecting-pipes 7 1,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses, this 22d day of November, A. D.1890.

PAUL D1 S'ITSINI.
